Disclosed herein are an optical lens and a light emitting module having the same. The disclosed optical lens includes a bottom surface, a recess upwardly convex at a central region of the bottom surface, a light input surface at a circumference of the recess, a first light output surface having a convexly curved surface at opposite sides of the bottom surface and the light input surface, and a second light output surface at a circumference of the first light output surface, wherein the bottom surface includes a first edge adjacent to the recess and a second edge adjacent to the second light output surface, a region of the bottom surface more adjacent to the first edge gradually approaches a first axis that is horizontal to a center of a bottom of the recess, and the first light output surface has a convex central region.
